Question

A shirt can be stiched using 2 1/4m of cloth.how many shirts can be stiched using 31 1/2m of cloth?

Answer 1

Let x₁=1,y₁=2 1/4 m = 9/4 m
x₂=x and y₂=31 1/2 m = 63/2 m
As number of shirts and amount of cloth are directly proportional,
x₁/x₂=y₁/y₂
⇒1/x=[(9/4)/(63/2)]
⇒1/x=1/14
⇒x=14 
Therefore,14 shirts can be stitched from 31 1/2 m of cloth.

Answer 2

14shirts can be stiched.
Hope it helps!
